+   * Parse and compile an expression.
+   * Returns a an object with a function `evaluate([scope])` to evaluate the
+   * compiled expression.
+   *
+   * Syntax:
+   *
+   *     math.compile(expr)                       // returns one node
+   *     math.compile([expr1, expr2, expr3, ...]) // returns an array with nodes
+   *
+   * Examples:
+   *
+   *     const code1 = math.compile('sqrt(3^2 + 4^2)')
+   *     code1.evaluate() // 5
+   *
+   *     let scope = {a: 3, b: 4}
+   *     const code2 = math.compile('a * b') // 12
+   *     code2.evaluate(scope) // 12
+   *     scope.a = 5
+   *     code2.evaluate(scope) // 20
+   *
+   *     const nodes = math.compile(['a = 3', 'b = 4', 'a * b'])
+   *     nodes[2].evaluate() // 12
